[PATCH] ahci boot failure

Fist of all - bug description:
On my notebook ThinkPad T400 Haiku loading sometimes hangs (probability of failure - 20-30%). Only if BIOS SATA mode - AHCI.
In case of BIOS SATA mode - Compatible, no problem to boot Haiku.
When Haiku booting hangs, simple call debuger and continue execution (Press SysReq Alt+D, then type "co" and press Enter). There are good chance, that "magic" will continue Haiku loading. If not, try this "calm" again and again...
There are no similar problems for Win and Linux on this computer.
lspci and syslog attached. Syslog contain two loading - bad and good.
Suggested solution: patch for ahci_port.cpp
Test it, please.
IMHO, this patch can be a solution for tickets: #4718, #4699, #3444 and #4004.
